Fault mirrors, a large disc, Cretaceous sand deposits and the vault of the cavity shaped by the advance of the Quaternary glaciers are all geological treasures that the cavity contains. Unlike the other underground nature reserves, it is the only one classified with the aim of protecting a strictly cavernicultural fauna other than bats, and for which we have old chronicles.
The cave is closed to the public all year round in order to preserve it because of its vulnerability. However, you can walk along the few existing paths and discover the cave with the help of signs.
